Final reassembly

[slocumjoseph]

Think I’ve finally got a handle on reworking the wiring for fitting a Renogy 50A DC-DC charger and MPPT controller ready for the installation of a solar panel when I have the readies in a month or so. After removing the large fridge unit had to cut out a lot of lining for access. Have never done any serious auto or domestic electrics before so it was a bit daunting but I think I’ve finally got a handle on it. My son has done a schematic of the setup now it’s getting to the final stage. Hopefully I’ll be fitting the cutout, cupboard and fridge back in the next few days so thought I would post a few pictures and the diagram in case the experts can see anything glaringly obvious or even dangerous. I’ll be a bit nervous of the great switch on, specially the reset EHU system. Or maybe I can meet up with a local expert like @Dellmassive who might be able to do a few tests. Alcohol as necessary.

Quick question, why have you got (From the diagram) a 100A and 60A fuse on the same line?



P.S. is that rockwool?

That 100amp fuse was on the original relay line fitted by the converters. It seems a bit over the top but I've left it in the diagram for any comments. I'v ealso just noticed I've got two negative coming from the controller. I think if the lower one was led round the top to the bus bar it would make more sense but the domestic fuse box would not be spliced into it.

Spotted a few more things...

1. you have fuses on the negative lines, did you have a reason?
2. fuse on the ignition live feed?


I'm not going to mention the picture of the leisure battery!

It looks a bit over fused. I put them in there simply because I saw other people had put some in their circuits. I'm hoping it's not necessary as it's pain cutting cable for a fuse and then finding places to put them. You can see I'll be push to get that lot back in the cupboard when I jggle it back to it's original position. The fuse on the ign was speculation. I'll be pleased if all those extras are not needed
Afraid the leisure battery is best I can afford.

I wasn't slagging off your leisure battery, all I meant was the image was wired the wrong way around (black to red, red to black).... sorry to confuse you!

Ha. Don't tell anyone but I'm colour blind Thanks for your input It's exactly what I needed

 

[Dellmassive]

I don't think you need these fuses on the main NEG.

Thanks. That's bit less hassle. Tomorrow I'll be working on getting that cutout piece back in place but made removable.
